Fix out-of-sync subtitles, edit dialogue timestamps, and repair broken captions on your Android device. SubShift is a fast, studio-grade subtitle editor and SRT synchronizer designed for movie lovers, video creators, translators, and anime fans. Whether your subtitles appear 2 seconds too early, lag behind dialogue, contain garbled foreign text, or drift out of sync over time, SubShift fixes your timing with millisecond precision. ━━━━━━━━━━━━━━━━━━━━━ ⚡ CORE TIMING & SYNC TOOLS ━━━━━━━━━━━━━━━━━━━━━ • Millisecond Timestamp Shifter: Shift all cues forward or backward (+/- seconds or milliseconds) to instantly eliminate audio-to-video delay. • Framerate Drift & Time Stretch: Fix progressive desynchronization caused by video framerate conversion (e.g., 23.976 FPS NTSC vs. 25 FPS PAL, 24 FPS to 29.97 FPS) using one-tap mathematical presets or custom multipliers. • Split & Merge Cues: Intelligently split long dialogue lines into two equal, properly timed blocks, or merge consecutive cues into a single subtitle. • Monospace Precision Display: View start times, end times, and exact durations in tabular monospace timecodes (HH:MM:SS,mmm) without visual jitter. ━━━━━━━━━━━━━━━━━━━━━ 🩺 SUBTITLE HEALTH & OVERLAP LINTER ━━━━━━━━━━━━━━━━━━━━━ Overlapping timestamps cause media players like VLC and Smart TVs to flicker, freeze, or skip lines. • Collision Detection: Automatically scans your subtitle file for overlapping timecodes, negative durations, and zero-length sub-flashes. • 1-Tap Auto-Fix: Resolves all timing collisions in one tap by clamping cue endings with a clean 50ms transition gap. ━━━━━━━━━━━━━━━━━━━━━ 📊 READING SPEED & CPS MONITOR ━━━━━━━━━━━━━━━━━━━━━ SubShift includes a Netflix- and BBC-standard Characters Per Second (CPS) monitor on every cue: • Normal (< 18 CPS): Optimal reading pace for viewers. • Fast (18–24 CPS): Elevated text density warning. • Too Fast (≥ 25 CPS): Immediate alert that viewers will struggle to read the text before the line disappears. ━━━━━━━━━━━━━━━━━━━━━ 🌐 ENCODING & FOREIGN CHARACTER REPAIR ━━━━━━━━━━━━━━━━━━━━━ Fix broken text, unreadable question marks, and garbled symbols: • Full Unicode UTF-8 auto-detection. • Arabic (Windows-1256). • Western European (ISO-8859-1). • ANSI Latin (Windows-1252). • Unicode Little/Big Endian (UTF-16LE / UTF-16BE). • Native Right-to-Left (RTL) support for Arabic, Hebrew, and Persian. ━━━━━━━━━━━━━━━━━━━━━ 💾 MULTI-FORMAT STUDIO EXPORT ━━━━━━━━━━━━━━━━━━━━━ • SubRip (.SRT): The universal standard for VLC, MX Player, Nova, and Smart TVs. • WebVTT (.VTT): Web standard with headers and millisecond dots, ready for YouTube, Vimeo, and web players. • Clean Transcript (.TXT): Export dialogue text stripped of cue numbers and timecodes for transcripts, blog posts, and study notes. ━━━━━━━━━━━━━━━━━━━━━ 📺 HOW TO USE YOUR EXPORTED FILE ━━━━━━━━━━━━━━━━━━━━━ 1. On VLC / MX Player: Open your video, tap the Subtitle icon, select your exported .srt file from your Downloads folder, and enjoy synced playback. 2. On Smart TVs & PCs: Place the video and the exported .srt file in the same folder with the exact same name (e.g., Movie.mp4 & Movie.srt). 3. On Social Video Editors: Import into CapCut, Premiere, or YouTube Studio to generate synced captions and closed captions. ━━━━━━━━━━━━━━━━━━━━━ 🔒 100% OFFLINE & PRIVACY-FIRST ━━━━━━━━━━━━━━━━━━━━━ SubShift runs entirely on your local device. Your subtitle files, transcripts, and video scripts are never uploaded to any remote server or third-party cloud.
